Type. Fish wanting head and anterior half of abdominal region ; 

 collection of James Powrie, Esq., Eeswallie. 



A species about 0-2 in length. Body much elongated ; spines 

 comparatively straight. Eour or five pairs of intermediate ventral 

 spines, separated by a distinct interval from the pelvic fin-spines ; 

 the latter more than half as long as the anal spine. First dorsal 

 spine shorter than the second, about midway between the pectoral 

 and pelvic pairs ; second dorsal spine much larger than the anal, 

 well in advance of the latter, almost opposed to the pelvic spines. 

 Lateral line with double series of enlarged scales. {Powrie.) 



Form. Sf Log. Lower Old Red Sandstone : Farnell, Forfarshire. 



Not represented in the Collection. 



The so-called Euthacanthus elegans, Powrie (torn. cit. 1870, p. 292, 

 pi. xii. fig. 5), is founded upon an imperfect impression of a fish from 

 Farnell, only differing from Climatius gracilis in the proportions of 

 some of the spines, which may be imperfectly shown. Another 

 species, Euthacanthus curtus, Powrie (ibid. p. 293, pi. xii. fig. 7), 

 from Turin Hill and Farnell, does not appear to belong to this 

 genus, and is doubtfully referred to Diplacanthus by Woodward and 

 Sherborn, Cat. Brit. Foss. Yertebrata (1890), p. 65. The type speci- 

 mens are in the collection of James Powrie, Esq.
